Spectrum Computing

It seems a weird beast to me. With 64KB of RAM and Z80 CPU it seems close to ZX Spectrum. Aside from the loading programs over serial, hardware wise it's a really just a bog-standard Z80/TMS-99x8/AY-3-8192/64k RAM machine much like a dozen other machines of that period. There was a floppy drive ava...

The vsbuild stuff is for building the binaries, so you probably don't want to use that. The link was to setting up vscode and has moved to here: https://bluebilby.com/developing-for-vz-part-2/ However, there's also this using vscode/clion: https://github.com/speccytools/z88dk-gdb-ide-test which incl...

Just as a note, I know Andy is using 1.99c for reasons, but if you're using a nightly/release from the past year or so, a lot of the topics that Andy has been covering in the series of articles are now available out of the box * WYZ player: https://github.com/z88dk/z88dk/tree/master/examples/sound/w...

I've still got the source disk for discdos, but it looks like there's some corrupt files so I don't think the latest version can be created from source. Actually...I'd moved over to cross assembling on an Amiga at some point in 1997/8 and my "highly efficient backup system" has shown up t...

I lurk in various places.... The original disc had a selection of other utilities on it by the looks of things. Most of the source code for them has ended up here: https://github.com/suborb/zx_disc_utils, alongside the slowdos source here: https://github.com/suborb/slowdos I've still got the source ...

[laughs] I have a feeling that bit of wrapper code isn't part of the "challenge". I think that code is actually trying to disassemble the following instruction, but the push ix gets in the way of that.

For a disassembler try this one: https://github.com/z88dk/z88dk/blob/mas ... disz80.asm - it's just over 1k in size so definitely one of the smaller ones. The code was extracted from Utility3 but the history goes back further than that.

Can't help with an assembler unfortunately.

I added support to appmake from z88dk to create "bootable" +3 discs a while back, it may be of use, though it is tuned for working with z88dk. appmake +zx --plus3 -b binary.bin --org=40000 Will create a .dsk image with the files "DISK" - short basic program to clear, load, rand u...

I think there's a bit of a context shift required for people coming to C on the Spectrum. UDGs are largely a concept from BASIC which don't make a lot of sense in the C world. C is much closer to assembly language, so you need to think at a lower level. OTOH, the stdio stuff is a high level concept...

Well, it comes with scripts "build.sh" and "config.sh". These have to be executable ("chmod +x ./build.sh", "chmod +x ./config.sh"). It compiles ok then, when you run "./build.sh" (OpenSuSE 13.1), no severe errors. Installation goes into "/usr/...

Doesn't quite work for me with latest nightly. On step 'Verify the Install': $ zcc +zx -vn test.c -o test -lndos warning: unknown option '-iquote.' warning: unknown option '-isystem/home/myuser/path/to/z88dk/lib/config/../..//include' spurious duplicate filename '/tmp/tmpXXkntuNK.i2' - vs. 'test.c'...
